Dental work and BFing

This is partly a vent too. We went on vacation this week, and yesterday, the last day of our vacation, I bit down on a piece of beef jerky and friggin' cracked my tooth! Like, a whole cuspid cracked off, and there's apparently a couple other cracks in it too. So the dentist wants to put a crown on it. He said it's not that involved of a procedure, just a local anesthetic. That's kosher with BFing, right? Didn't bother asking him, cause I figured there's gotta be someone here that's been in a similar situation, right? Just wanted to make sure.. Thankfully it's one of my molars and not one of my front teeth or anything, since they can't get me in the repair it until closer to the end of the month. Grrr...
